Effect of nitrogen limitation and nature of the feed upon Oenococcus oeni metabolism and extracellular protein production

2005

Aims:  The aim of the study was to characterize the effect of various nitrogen sources on Oenococcus oeni growth, carbon source utilization, extracellular protease activity and extracellular proteins. More generally, the goal is to understand how nitrogen-based additives might act to enhance malolactic fermentation in wine. Methods and Results:  Five yeast extracts were used. As the amino acid and nitrogen analyses revealed, they were similar in global amino acid composition, except for arginine level. Nevertheless the ratio of amino acids between free/bound, and low/high molecular weight fractions were highly different. One of the yeast extracts led to a significant protease activity in th…

Jatkosodan retoriikka : argumentaatioanalyysi pääministeri Rangellin ja pääministeri Linkomiehen puheista

2009

Tutkimuksen tehtävänä on selvittää, millaista retoriikkaa Suomen jatkosodan aikaiset pääministerit JW Rangell sekä Edwin Linkomies puheissaan käyttivät. Tarkastelen tutkimuskysymystä analysoimalla kaksi puhetta, joista toisen puheen piti Rangell syksyllä 1941. Toinen on Linkomiehen kesällä 1944 pitämä puhe. Analysoin puheet erittäin tarkasti käyttämällä metodina valtio-opin alalla yleistä argumentaatioanalyysia. Pääasiallisena teoreetikkona käytän Chaim Perelmanin retoriikkatutkimusta ja tukena myös Aristoteleen Retoriikka-teosta sekä uudempaa retoriikka- ja sotaretoriikkatutkimusta. Aineistona työssä ovat puheet, jotka ovat kokonaisuudessaan myös gradussa mukana. Tutkimus osoittaa, että su…

Increasing chains and discrete reflection of cardinality

2013

Combining ideas from two of our previous papers, we refine Arhangel'skii Theorem by proving a cardinal inequality of which this is a special case: any increasing union of strongly discretely Lindelof spaces with countable free sequences and countable pseudocharacter has cardinality at most continuum. We then give a partial positive answer to a problem of Alan Dow on reflection of cardinality by closures of discrete sets.

Infinite games and cardinal properties of topological spaces

2015

Inspired by work of Scheepers and Tall, we use properties defined by topological games to provide bounds for the cardinality of topological spaces. We obtain a partial answer to an old question of Bell, Ginsburg and Woods regarding the cardinality of weakly Lindel¨of first-countable regular spaces and answer a question recently asked by Babinkostova, Pansera and Scheepers. In the second part of the paper we study a game-theoretic version of cellularity, a special case of which has been introduced by Aurichi. We obtain a game-theoretic proof of Shapirovskii’s bound for the number of regular open sets in an (almost) regular space and give a partial answer to a natural question about the produ…

Cardinal invariants of cellular Lindelof spaces

2018

A space X is said to be cellular-Lindelof if for every cellular family $$\mathcal {U}$$ there is a Lindelof subspace L of X which meets every element of $$\mathcal {U}$$ . Cellular-Lindelof spaces generalize both Lindelof spaces and spaces with the countable chain condition. Solving questions of Xuan and Song, we prove that every cellular-Lindelof monotonically normal space is Lindelof and that every cellular-Lindelof space with a regular $$G_\delta $$ -diagonal has cardinality at most $$2^\mathfrak {c}$$ . We also prove that every normal cellular-Lindelof first-countable space has cardinality at most continuum under $$2^{<\mathfrak {c}}=\mathfrak {c}$$ and that every normal cellular-Lindel…

Aristotele e Dante, filosofi della variabilità linguistica

2010

Diversamente da quanto si legge in letteratura, Aristotele fu un filosofo che ha messo a fuoco le cause naturali della variabilità, nel tempo e nello spazio, delle lingue verbali. Dante, pur non conoscendo la lingua greca e potendo accedere alle opere aristoteliche tramite le traduzioni latine, teorizza il linguaggio in sintonia con questo aspetto della filosofia aristotelica. Nel saggio si mette in luce la somiglianza tra la locutio vulgaris teorizzata nel De vulgari eloquentia e la nozione di dialektos descritta da Aristotele nelle opere biologiche. Vengono anche esaminate le ragioni aristoteliche del motivo per cui secondo Dante gli angeli non hanno bisogno di locutio vulgaris e quindi n…

Religious and spiritual motifs in the art of the patients of Nikkilä Hospital

2021

This article focuses on religiousness and spirituality in the art works of psychiatric patients of Nikkilä Hospital, Finland. The pictures analysed here belong to a collection held at the Helsinki City Museum and they were made during the twentieth century. The theoretical frame of the study is a cultural study of mental health. The collection is approached as presenting a specific kind of imagery which has connections not only to the personal history and diagnoses of the patients; their cultural context and hospital environment is also taken into account. The religiousness and spirituality of the Nikkilä collection are also compared with outsider art and examples of art history internation…

Can Paintings Talk? An Ekphrastic Polemic in Post-Stalin Russia

2016

Il “romanzo-pamphlet” di Ivan Ševcov Tlja (“Il pidocchio” o “L’afide”, 1964) è noto come la “pasquinata” (A. Sinjavskij) di un reazionario nostalgico dello stalinismo che si scaglia contro le timide aperture culturali del disgelo Chruščeviano. La diagnosi è indiscutibile; un motivo di interesse risiede però nell’uso peculiare dell’ékphrasis (il romanzo, ambientato nel mondo degli artisti figurativi, può essere letto come una grande galleria di dipinti immaginari) e, per di più, nel fatto che oggetto del contendere è la possibilità stessa dell’ékphrasis, la capacità dei dipinti di essere portatori di un contenuto esprimibile a parole – questo è l’oggetto ultimo della polemica sotterranea che…
